A form found in unstructured languages, mimicking a typical machine code instruction, would jump to (GOTO) a label or line number when the condition was met. IF..THEN..(ENDIF) . Rather than being restricted to a jump, any simple statement, or nested block, could follow the THEN key keyword.
Scala runs on the Java platform (Java virtual machine) and is compatible with existing Java programs. [15] As Android applications are typically written in Java and translated from Java bytecode into Dalvik bytecode (which may be further translated to native machine code during installation) when packaged, Scala's Java compatibility makes it well-suited to Android development, the more so when ...
In this case the usual shell syntax is used for the word (“here string syntax”), with the only syntax being the redirection: a here string is an ordinary string used for input redirection, not a special kind of string. A single word need not be quoted: $

In order to construct a token, the lexical analyzer needs a second stage, the evaluator, which goes over the characters of the lexeme to produce a value. The lexeme's type combined with its value is what properly ...
